Assessment of the Effects of Structural Modification of Gastrodia elata Polysaccharide on Anti-Breast Cancer Activity Using Asymmetrical Flow Field-Flow Fractionation

open access: yesMolecules, 2023
Gastrodia elata (“Tian Ma” in Chinese) is used as a food and medical ingredient in traditional Chinese medicine. In this study, to enhance the anti-breast cancer activity of Gastrodia elata polysaccharide (GEP), GEPs were modified via sulfidation (SGEP ...

Brain–Behavior Relationships in Children With ADHD: Resting‐state EEG Networks Underlying Executive Function and Neurological Soft Signs

open access: yesBrain and Behavior, Volume 16, Issue 8, August 2026.
ABSTRACT Purpose To investigate sex‐stratified brain–behavior relationships between large‐scale functional brain network topology and executive‐motor profiles in pediatric ADHD, using a multi‐dimensional parameter exploration approach. Method Graph‐theoretical connectivity measures were derived from resting‐state EEG in 41 medication‐naïve children ...

Dynamic Hemispheric Lateralization of Naturalistic Emotional Processing After Unilateral Stroke: An EEG Study

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 8, August 2026.
Unilateral stroke differentially disrupts dynamic hemispheric lateralization during naturalistic emotional viewing. Left‐hemisphere stroke showed persistent parietal‐theta states, whereas right‐hemisphere stroke showed positive‐context variability, stronger arousal–switching coupling, and blunted positive affect.

Microfluidic nanochips for rapid exosome isolation and multiplex biomarker profiling from a single blood drop: Toward sample‐to‐answer liquid biopsy

open access: yesClinical and Translational Discovery, Volume 6, Issue 4, August 2026.
A microfluidic nanodevice that analyses a single volume droplet of whole blood (10–50 microlitres (µL)) forms a fast and fully integrated exosome‐derived liquid biopsy. The closed system architecture involves plasma separation on chip, exosome enrichment by immunoaffinity and various size based, electrokinetic, acoustofluidic or hybridized strategies ...

Exhumation History of the Sangre de Cristo Range, Colorado, From Mid‐ to Low‐Temperature Thermochronology: New Insights Into Laramide Contraction and Oligocene–Miocene Extension in the Northern Rio Grande Rift, USA

open access: yesTectonics, Volume 45, Issue 8, August 2026.
Abstract The Sangre de Cristo Range in southern Colorado records a complex tectonic history that includes Late Cretaceous–Eocene Laramide contraction and Oligocene–Quaternary Rio Grande rift extension. We present new thermochronologic data (40Ar/39Ar, fission‐track, (U‐Th)/He) and thermal history models that provide insight into this polyphase history ...

Blocking SETD2 Enhances the Therapeutic Efficiency of Menin Inhibitor in MLL‐Fusion Leukemia

open access: yesCancer Science, Volume 117, Issue 8, Page 2221-2235, August 2026.
Combined SETD2 and menin inhibitors make synergistic effects against MLL‐fusion leukemia; the combination therapy reduces the expression of target genes through blocking transcription elongation and initiation. ABSTRACT During transcriptional elongation, the histone methyltransferase SETD2 binds to RNA polymerase II and deposits trimethylation marks at

Mll-AF4 Confers Enhanced Self-Renewal and Lymphoid Potential during a Restricted Window in Development

open access: yesCell Reports, 2016
MLL-AF4+ infant B cell acute lymphoblastic leukemia is characterized by an early onset and dismal survival. It initiates before birth, and very little is known about the early stages of the disease’s development.

Changes in Aperiodic (1/f Slope) Activity During a Picture‐Word Interference Task: Effects of Congruency and Sequence Manipulations

open access: yesPsychophysiology, Volume 63, Issue 8, August 2026.
ABSTRACT Aperiodic neural activity (1/f EEG) has been proposed to reflect the balance between excitatory and inhibitory (E/I) inputs, with steeper spectral slopes reflecting increased inhibition and flatter slopes indicating excitation. This activity is also thought to reflect the temporal coordination of neural firing, offering insights into ...

Challenges in Determining the Size Distribution of Nanoparticles in Consumer Products by Asymmetric Flow Field-Flow Fractionation Coupled to Inductively Coupled Plasma-Mass Spectrometry: The Example of Al2O3, TiO2, and SiO2 Nanoparticles in Toothpaste

open access: yesSeparations, 2018
According to the current European regulation on cosmetics, any ingredient present as a nanomaterial should be indicated in the ingredient list. There is a need for analytical methods capable of determining the size of the relevant ingredients and thus ...
